Role of toll-like receptors and their ligands in adipocyte secretion

Published on: 8th April, 2021

OCLC Number/Unique Identifier: 9031345560

Background: Adipose tissue is one of the main sites of energy homeostasis that regulates whole body metabolism with the help of adipokines. Disruption in its proper functioning results in adipose tissue remodeling (primarily hypertrophy and hyperplasia) which directly influences the secretion of said adipokines. Obesity characterized as chronic low-grade inflammation of the adipose tissue is one such condition that has far reaching effects on whole body metabolism. Inflammation in turn results in immune cells infiltrating into the tissue and further promoting adipocyte dysfunction. Purpose: In our study we explored this adipose tissue-innate immunity axis by differentiating adipose tissue derived stem cells (ADSCs) into white and beige adipocytes. We further stimulated our cultures with lipopolysaccharide (LPS), flagellin, or meteorin-like, glial cell differentiation regulator (METRNL) to trigger an inflammatory response. We then evaluated Toll-like receptor (TLR) mRNA expression and secretion of interleukin (IL-6), interleukin-8 (IL-8), brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF) in these cultures. Results: We found that TLR2 is the highest expressed receptor in adipocytes. Further, LPS and METRNL are strong activators of TLR2 in white and beigeBMP7(-) adipocytes. TLR4 was not significantly expressed in any of our cultures despite LPS stimulation. TLR9 expression is upregulated in ADSCs upon LPS and METRNL stimulation. IL-6 and IL-8 secretion is increased upon LPS stimulation in white adipocytes. METRNL activates both IL-6 and IL-8 expression in adipocyte cultures. Lastly, BDNF and NGF is secreted by all adipocyte cultures with beigeBMP7(-) and beigeBMP7(+) secreting slightly higher amounts in comparison to white adipocytes. Conclusion: ADSCs and adipocytes alike are capable of expressing TLRs, but white adipocytes remain the highest expressing in both control and stimulated cultures. TLR2 is highly expressed in white and beige adipocytes whereas TLR4 showed no significant expression. LPS and METRNL trigger IL-6 and IL-8 secretion in adipocytes. Products of white adipocyte “browning” are capable of secreting higher amounts of BDNF and NGF in comparison to white adipocytes.

Importance of BLUP method in plant breeding

Published on: 31st May, 2022

OCLC Number/Unique Identifier: 9526112251

Introduction: The most desirable linear neutral prediction (BLUP) is a standard method for estimating the random effects of a hybrid model. This approach was originally developed in animal breeding to estimate breeding values and is now widely used in many fields of research. The main practical advantages of using REML/BLUP are: It allows the comparison of individuals or species over time (generation, year) and space (location, block). Possibility of simultaneous correction of environmental effects, estimation of variance components, and prediction of genetic values.The best BLUP prediction method, which estimates the averages with high accuracy, especially in mixed models, is also used to evaluate multi-environment experimental data (MET).Blup is one method is statistical. Pedigree-based blup method.Materials and methods: The BLUP method achieves this goal by combining phenotypic data and information on pedigree relationships through an index, known as family index selection. This index, which is estimated based on the coefficient of intra-class correlation, exploits the relationships of individuals within a family compared to other families in the population.Results: The results: show that BLUP has good prediction accuracy compared to other methods. Pedigree-based BLUP method can increase selection yield in production-related traits in P. zonale or shelf life of D. caryophyllus L.

Prostatic inflammatory myofibroblastic tumor: 2-case report with literature review

Published on: 29th January, 2019

OCLC Number/Unique Identifier: 7991649051

Inflammatory myofibroblastic tumor is rarely seen in the prostate. Most of prostatic tumors are benign. However, local aggressively invading the adjacent organs and recurrence are frequent. Rarely, the malignant transformation and metastasis occurs, especially in elderly patient. The definitive diagnosis in a small biopsy is challenging. The correct diagnosis preoperatively will help to avoid unnecessary radical prostatectomy. Interval follow up is recommended. Here we reported two cases of prostatic inflammatory myofibroblastic tumor with literature review.

Nursing Care of ICU Patients Lightly Sedated with Dexmedetomidine

Published on: 22nd December, 2016

OCLC Number/Unique Identifier: 1026798761

Background: Intensive care patients are often in need of sedation to endure being intubated. Light sedation is increasingly common since it has been proved to offer benefits such as faster recovery to patients. Aim: The aim of this study was to describe critical care nurses’ experiences of nursing patients lightly sedated with dexmedetomidine. Research Methodology: Qualitative personal interviews were conducted during 2015 with 10 critical care nurses in Sweden. Interview transcripts were analysed using inductive qualitative thematic analysis. Results: Light sedation of the patient facilitated communication and interaction with him or her, and the relationship between the patient and his or her family members. Dexmedetomidine was described as a fairly new drug, and the critical care nurses stated that they needed more knowledge about it and about sedation scales in order to learn more about the drug’s mechanism of action and its potential side effects on patients. Conclusion: It is important to critical care nurses to learn more about dexmedetomidine and about sedation scales to assess levels of sedation, as light sedation has been shown to benefit the patient as opposed to deep sedation that can increase recovery time.

Longitudinal and transverse dimensions of hypertrophied cardiomyocytes in human left ventricle (LV) at autopsy; Heart failure might result from changes in chamber geometry without contractile weakening

Published on: 23rd July, 2019

OCLC Number/Unique Identifier: 8192127540

The shapes and sizes of human cardiomyocytes are accessible to systematic observation under most circumstances only at autopsy. This constraint has seriously curbed the study of these topics, thereby leaving a crippling gap in our understanding of heart failure. In recent years the only published ongoing findings have come from this laboratory. This article is a condensation of these reports, using those sources to develop fresh analyses designed to construct a set of organizing principles. The data are entirely retrospective thereby forbidding hypothesis testing and permitting only hypothesis formation. The hypotheses generated in this way are novel and surprising. In spite of the severe limitations in this methodology is seems possible that some useful new directions of inquiry might evolve from pursuing these original observations.

Knowledge, attitude and practices associated with diagnosis and management of Skin and Soft Tissue Infections (SSTIs) among Pediatric Residents and Physicians in a Tertiary Hospital in United Arab Emirates (UAE)

Published on: 11th July, 2017

OCLC Number/Unique Identifier: 7317652483

Objectives: The study aims to assess the knowledge, attitude and practices of physicians who deal with pediatric age group SSTIs in reference to the Infectious Diseases Society of America (IDSA) guidelines on this regard that was published in 2014. Background: Skin and soft tissue infections rank among the most frequent infections worldwide. It is estimated that over 11 million ambulatory healthcare visits occur each year in US for skin and soft tissue infections due to Staphylococcus aureus (S. aureus) alone. SSTIs are clinical entities of variable presentation, etiology and severity that involve microbial invasion of the layers of the skin and underlying soft tissues. SSTIs range from mild infections, such as pyoderma, to serious life-threatening infections, such as necrotizing fasciitis. One of the main challenges in managing SSTIs is to be able to identify those who need immediate inpatient intervention versus the more stable ones that can be manages in outpatient basis. In June of 2014, The Infectious Diseases Society of America (IDSA) released evidence based guidelines that has nicely covered all aspects related to the management of SSTIs. Method:An anonymous 20-item survey exploring knowledge, attitude and practices associated with diagnosis and management of skin and soft tissue infection was distributed to physicians of different levels of expertise (from residents to consultants) in the departments of Pediatrics, Emergency Medicine and Family Medicine in different governmental facilities in Al-Ain city which is one of the major cities in United Arab Emirates.

The Neppe-Close triadic dimensional vortical paradigm: An invited summary

Published on: 13th January, 2020

OCLC Number/Unique Identifier: 8529693639

Physicists are generally trained in the Standard Model of Physics (SMP). This implies that they perceive and account for only 3 dimensions of space in a moment in time (3S-1t) (a 4-dimensional [4D] model). However, applying the SMP, more than fifty significant conundrums have arisen that are unexplained or incomplete. Explaining these within the SMP 4D fabric led to hypothesizing a ‘fifth force’, most recently the hypothetical ‘X17 particle’. We propose this hypothetical X17 may better be explained by a 9-dimensional model (9D) with gimmel. Our model, the Neppe-Close Triadic Dimensional Vortical Paradigm (TDVP) has amplified the ‘physics’ from 4 dimensions to 9D, specifically first postulating and then further demonstrating mathematically—starting with derivations of the Cabibbo angle—that 9 dimensions must exist. Moreover, this data is empirically demonstrated because the neutron, proton and electron mass-energy-gimmel equivalence in the Triadic Rotational Units of Equivalence (TRUE) as part of the TDVP model, exactly corresponds with the normalized data for the mass-energy equivalence volumetric data for these particles in the CERN Large Hadron Collider. This data shows definitively that we exist in a 9-dimensional finite, quantized, volumetric, spinning reality. This is, furthermore, embedded in an infinite continuity (9D+). Mathematically, applying this 9D+ model definitively requires an extra third component that is massless and energyless (‘gimmel’). Without gimmel, no particle in the universe would be stable. TDVP unifies nature because the same laws apply across the quantum, macro-world and cosmological reality. Our 4D experience is simply the physical component of 9D+ existence. Summary Amplification: At all levels, there is the consistent application of a 9-Dimensional quantized finite reality embedded within an infinite continuity. The application of gimmel specifically requires applying the 9-dimensional model and is based on necessary mathematical calculations not only at the quantal level (where the fifty plus unsolved, unexplained or contradictory conundrums can be explained somewhat, and there is no longer ‘quantum weirdness’), but at the macroscale level with more gimmel in the life elements (which, additionally, are consistently all cubic multiples of 108 cubed), as well as cosmologically, where the correlations with proportionate Dark Matter and Dark Energy are overwhelming. Moreover, these 9-dimensional plus factors together with Triadic Rotational Units of Equivalence (TRUE) and gimmel, allow numerous solutions that couldn’t otherwise be solved. For example, importantly, applying the simple mathematics of TRUE, we can demonstrate why gluons, while adequate in 4D, are impossible applying 9D. These solutions are simpler because we have markedly adapted George Spencer-Brown’s ‘Laws of Form’ to applying a new method of mathematical calculation, Edward Close’s ‘Calculus of Distinctions’ (COD) which recognizes quantal limits and that the nature of finite reality is quantized and volumetric. The COD includes distinguishing between content, extent, and impact. We emphasize the pioneering works of Wolfgang Pauli with his multidimensional model and his ‘Pauli Exclusion Principle’, Alfred Whitehead with ‘Process Philosophy’ and his ‘Principia Mathematica’ (with Bertrand Russell), Georg Cantor with Set Theory, and Roger Penrose with spinors and twistors. TDVP is a prime example of our broad new specialty of ‘Dimensional Biopsychophysics’ (DBP). DBP extends physics, consciousness, and the biopsychosocial to extra dimensions and applies mathematics empirically. Like Max Tegmark, we recognize the key role of mathematics as fundamental in nature, not just for application in calculation and operations.
